ISLE AU HAUT, Maine — The 40 year-round residents of this remote, wind-swept island about six miles off the Maine coast are looking for some adventurous souls to join their community, contribute to its civic life, and fill the one-room schoolhouse with children.

To woo new neighbors, Isle au Haut’s leaders have secured a $355,000 state grant to build two affordable rental homes — one amidst blueberry patches and spruce trees, the other offering glimpses of the rocky coast — for families of four earning less than $70,000 a year.
